Antoine Pitrou commented on ARROW-555:
--------------------------------------
I think going through LLVM IR is a bit convoluted. More simply, since those
functions are already raw C in Gandiva, we could reintegrate those C functions
somewhere in Arrow (taking care that the Gandiva toolchain can still compile
them to LLVM bitcode).
It would also avoid depending on LLVM for builds with Gandiva disabled.
